Après essais et erreurs, je peux suggérer ce qui suit:

Sudo apt-get install python3-pip python3-pyqt4 \
                     python3-pyqt5 python3-pyqt5.qtsvg python3-pyqt5.qtwebkit
Sudo pip3 install -U spyder

Le résultat: Spyder3 est installé et sa fenêtre À propos de Spyder contient

Spyder 3.2.4
...
Python 3.5.2 64bits, Qt 5.5.1, PyQt5 5.5.1 sur Linux

Testé sur une installation propre de Ubuntu 16.04.3 LTS AMD64.
